30 seconds for disinfection

The researchers exposed Sars-Cov-2 viruses for 30 seconds to the WHO-recommended disinfectant formulations. "This time frame was chosen based on recommendations for hand disinfectants," says Stephanie Pfänder.

Subsequently, the team tested the viruses in cell culture assays and analyzed how many viruses remained infectious. "We showed that both WHO-recommended formulations sufficiently inactivate the virus after 30 seconds," as Stephanie Pfänder sums up the results. Plus, this does not merely apply to the WHO solutions; rather, their main components, the alcohols ethanol, and isopropanol, also showed adequate inactivation of the virus.

WHO-recommended formulations

The disinfectant I recommended by the WHO consists of 80 volume percent ethanol, 1.45 volume percent glycerine, and 0.125 volume percent hydrogen peroxide. Disinfectant II consists of 75 volume percent isopropanol, 1.45 volume percent glycerine, and 0.125 volume percent hydrogen peroxide.

German Pharmacies allowed to sell WHO-II formulation

Following the amendments to the German Drug Law by the German government on Wednesday, March 4, 2020, that will remain in effect for six months, the formulation WHO II, which is based on isopropanol, has been approved for this period. As a result, pharmacies are permitted to produce and sell this formulation in order to alleviate the current shortage of disinfectants.
